Iterate/Loop over a JSON structure

This is an example for looping JSON structure and reading values.

var s = [{key:1,value:"abc"},{key:2,value:"def"},{key:3,value:"xyz"},{key:1,value:"pqr"}]

for(var i in s)
    console.log ("Key :" + s[i].key + " - Value :" + s[i].value)

//Output
Key :1 - Value :abc
Key :2 - Value :def
Key :3 - Value :xyz
Key :1 - Value :pqr

File Row Count using Batch file in a directory

Copy and Paste following code in a batch file, that will count rows in file (csv, txt, etc.,) available in the directory.

@ECHO OFF
setlocal enabledelayedexpansion
for %%f in (*.csv) do (
  set /p val=<%%f
  find /v /c "" %%f
)

Row count with DOS "Find Command"

Windows find command :

Using ‘Find’ command,  we can search for specific text in a set of files. Find below the syntax of this command with examples. Note that windows find command is different from the Linux find command in functionality. Linux find command is used to search for files that match the given criteria. But the windows find command is useful to search files for the lines that match the given string. The windows command that matches partially with Linux find command’s functionality is dir command.

Syntax and Examples

Find the lines of a file that have the specified string
find "string" filename
Ex:

C:\>find "Windows" C:\boot.ini
---------- C:\BOOT.INI
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect


To print line numbers along with the lines
find /N "string" filename
Ex:

C:\>find /N "Windows" C:\boot.ini
---------- C:\BOOT.INI
[5]multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect



To ignore case in searching for the string, we can add /I switch.
find /I /N "string" filename
In the below example, we don’t find any matching lines when we search for ‘windows’. In the next command, I have added /I and it shows the matching line ignoring the case differences.

C:\>find /N "windows" C:\boot.ini

---------- C:\BOOT.INI

C:\>find /N /I "windows" C:\boot.ini

---------- C:\BOOT.INI
[3]default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[5]multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect


To find the lines that are not matching with the given string:
We can use /V switch for this case. Please find the command syntax below.

find /V  "string" filename
Ex:

C:\>find /N "windows" C:\boot.ini
---------- C:\BOOT.INI

C:\>find /N /I "windows" C:\boot.ini

---------- C:\BOOT.INI
[3]default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[5]multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

How to use Filter with JSON Data

// JSON Data

var jd = JSON.parse('[{"status":"Pass","Marks":98,"subject":"English"},{"status":"Pass","Marks":99,"subject":"Math"},{"status":"Fail","Marks":32,"subject":"Science"},{"status":"Fail","Marks":30,"subject":"History"},{"status":"Pass","Marks":95,"subject":"Computer"}]')


// use filter property to get each item with the condition match as Status as PASS (we are using === to validate they type and return if condition get true.)

var fd = jd.filter(function(item){
      return (item.status === "Pass");
});

result will be.

fd = [{"status":"Pass","Marks":98,"subject":"English"},{"status":"Pass","Marks":99,"subject":"Math"},{"status":"Pass","Marks":95,"subject":"Computer"}]

Integer value with leading zero using JavaScript

prefix_zero(10,4) // output 0010

function prefix_zero(num, size) {
    var s = num+"";
    while (s.length < size) s = "0" + s;
    return s;
}

SharePoint Designer 2010 - Set Variable [Today]-x Days

To set a DateTime field to [Today] + 5 days using a SharePoint Designer 2010 Workflow, this is what I did:


1) Create a Local Variable (ETA Date) of type Number
2) Use a Do Calculation task in the workflow and set:

value: Workflow Context:Date and Time Last Run (As Double)
operation: plus
value: 432000 (number of seconds in 5 days or 60*60*24*5)
Output to: Variable: ETA Date

3) Finally, set the value of the respective field of the current item to the ETA Date variable

In your case, use the subtract operation and the second value is 2419200 (60*60*24*28).

Note: Compare the Date in Workflow, Current Item:ReminderDate equals (ignoring time) Today
